Everything happening now, with the FDA and in Congress, is prelude to a world of tightly controlled, highly profitable nicotine addiction products. It's our future.
This maybe the plan and would probably have succeded if nicotine 'addiction' was the same as other addictions. It does seem there are a number of differences otherwise NRT would be more effective.
Just reading here it is becomes obvious that people's interaction with nicotine differs. Some instantly transfer to e-cigs, others continue with tobacco, yet others are able to go to zero nic cartridges while some go the other way. PVs cause such consternation because people do not need to vape nicotine at all.
This diversity is somewhat perplexing. One scenario, as you suggest is highly profitable nicotine products, perhaps a transfer from BigT to BigP or BigP nic and heavily taxed BigT products. This isn't going to be easy. The black market is growing (Ireland recently backed off a tax rise because of this) and NRT products, dispite heavy promotion, are still not always a free choice people make. Strange really if Nicotine is so addictive.
The other strange phenomenon is increasing smoking rates, after a short dip when bans come in. This has been seen in Ireland and the UK.
The future is uncertain and people will make their own chocies. A reading of history suggests that a period of aquiesence will be followed by a change. PVs may be part of that change or maybe not. Whatever happens the continued coercive tactics do not seem to be working as well as they apparently should, if nicotine were like any other addictive drug.
